<br /> Appendix - DateValue Input Type - 1 <br /> <br />Appendix: DateValue Input Type <br />20 1 2 -0 4 -0 5 <br />Overview <br /> <br />The DateValue time series file format can be used to store one or more time series of consistent time <br />interval. The format has been developed to facilitate data management and processing with the TSTo ol <br />software . The example below shows the format of the file. Important comments about the file format <br />are: <br /> <br />• The file is divided into a header section with time series properties (top) and data section (bottom). <br />Comments can occur anywhere in the file an d are lines that start with #. <br />• The default delimiter between property columns and data columns is a space. Use the Delimiter <br />property to reset the delimiter (e.g., to a tab). Adjacent delimiters WILL NOT be merged into one <br />column ; consequently, do not use extra delimiters (i.e., whitespace) to format output . <br />• If not specified, many of the header properties will be set to reasonable defaults as data are read by <br />software such as TSTool. However, as much information as possible shoul d be specified to allow <br />complete time series handling. Header information is displayed by applications like TSTool to allow <br />selection of time series before the data section is read. <br />• If multiple irregular interval time series are stored in the file, non -overlap ping date/times will result in <br />blanks rather than the missing value indicator (missing value indicators indicate actual values in the <br />irregular time series ; “missing ” values are allowed to have data flags , whereas “no value ” a re <br />represented as blanks ). <br />• Properties names are case -independent. <br />• The TSID , Start , End , and Units pr operties are important for basic time series handling. <br />o The interval part of the TSID is used to determine how memory should be allocated for data. <br />o The Start and End values are used to allocate memory for regular interval time series. Dates <br />associated with data values are used to allocate memory for irregular interval time series. <br />o For regular interval time series, if data lines between the start and end dates are omitted, the <br />unspecified values are set to the missing data value for the time series. <br /> <br /># DateV alueTS 1.1 file <br /># <br /># This is a sample of a typical DateValue minute time series. An <br /># example file is as follows and conforms to the following guidelines: <br /># <br /># * Comments are lines that start with #. <br /># * Applications often add a comment section at the top i ndicating how the <br /># file was created <br /># * Any line that starts with a number is assumed to be a data line. <br /># * Time hours should be in the range 0 to 23 (an hour of 24 will be <br /># converted to hour 0 of the next day). <br /># * If a time is necessary, the date/time may be separated by a space, T, :, or <br /># @. If a space is used, use date and time column headings. <br /># * If multiple time series are written, header variables are delimited with <br /># space or tab characters. Data are delimited as per the Delimiter pro perty . <br /># * Time series are required to have the same data interval. <br /># * Header property values and column headers can be enclosed in double quotes <br /># if the data contain spaces. <br /># * Missing data can either be coded as the missing data value or no value . <br /># * Missing records will result in missing data being used when read. <br /># <br /># The following header variables are recognized.
